Just fired my Sandman S the other day. 300BO Subsonic is real nice. Currently running a 12″ barrel but maybe cutting it back to 9″. Super sonic was ok but Fiocchi 150 Factory FMJ blows primers due to back pressure. Armscor 150 worked fine…..not as hot. All operated perfect though. Ran the Sandman S on my 16″ AR-10 and it is quieter. Going to try on my SCAR 17 next. The 300BO is fun to load for also. Need to find inexpensive 200g .30 cal. Have a ton of 150 and 173…..maybe a reduced load that functions will be next. This is my first can so I’m a rookie here.
